Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0032] like Figures 1 to 5 As shown, this utility model embodiment provides a surgical forceps, including a housing 1, a forceps head 2, an operating handle 3, a linkage mechanism 4, a suction tube 5, and a negative pressure generating device 6. The forceps head 2 is located at one end of the housing 1; the operating handle 3 is located at the other end of the housing 1; the linkage mechanism 4 connects the operating handle 3 and the forceps head 2, and the operating handle 3 is used for a person to hold and drive the forceps head 2 to open and close; the suction tube 5 is connected to the housing 1, and the suction tube 5 has at least one open end 51, which faces the forceps head 2; the negative pressure generating device 6 is connected to the suction tube 5. Specifically, the specific operating principle of this utility model is as follows: During the surgical operation, the doctor holds the operating handle 3, with the open end 51 of the suction tube 5 facing the surgical site, and then activates the negative pressure generating device 6. The negative pressure generating device 6 generates negative pressure, which draws blood or foam from the surgical site from the open end 51, thereby exposing foreign objects at the surgical site. Then, the opened forceps head 2 is aligned with the foreign object to be clamped. Next, press the operating handle 3. The operating handle 3 drives the clamp head 2 to close via the linkage mechanism 4. The clamp head 2 clamps the foreign object, and the doctor removes the foreign object from the surgical site, completing the surgical procedure. Specifically, the negative pressure generating device 6 is a compression airbag or a negative pressure suction machine, which is connected to the suction tube 5 via a detachable interface.

[0033] In one optional embodiment of this invention, the suction pipe 5 includes a pipe body 52 and a filter screen 53. The pipe body 52 has an open end 51, and the filter screen 53 is connected to the pipe body 52 and covers the open end 51. The filter screen 53 can block foreign objects from entering the pipe body 52 and preventing them from clogging the pipe.

[0034] As one optional implementation of this embodiment, the filter screen 53 is hemispherical. The hemispherical shape of the filter screen 53 can reduce the contact area between the filter screen 53 and foreign objects, so as to ensure that there are still filter holes in the circumference of the hemispherical filter screen 53 that allow blood foam or blood to pass through, thereby reducing the possibility of the filter screen 53 being completely blocked.

[0035] As one optional implementation of this embodiment, the operating handle 3 includes a first handle 31 and a second handle 32. The first handle 31 is fixedly connected to the housing 1, and the second handle 32 is connected to the linkage mechanism 4 and hinged to the first handle 31. The second handle 32 can rotate relative to the first handle 31, thereby realizing the operation of the operating handle 3.

[0036] As one optional implementation of this embodiment, the operating handle 3 further includes a spring plate 33, one end of which is connected to the first handle 31, and the other end of which is connected to the second handle 32. The spring plate 33 has a certain elasticity, and when the operating handle 3 is not held, the second handle 32 can automatically reset under the action of the elastic force provided by the spring plate 33.

[0037] In one optional embodiment of this invention, the first handle 31 has a grip ring 311 forming an annular grip portion, and the second handle 32 has a limiting protrusion 321 to restrict the sliding of the hand. The grip ring 311 is for the fingers of the hand to pass through for gripping, and the limiting protrusion 321 can prevent the hand from sliding upwards during gripping.

[0038] In one optional embodiment of this invention, the pliers 2 includes a first clamping head 21 and a second clamping head 22. Both the first clamping head 21 and the second clamping head 22 are rotatably connected to the housing 1, and their ends are connected to the linkage mechanism 4. The first clamping head 21 and the second clamping head 22 can be relatively close to each other to achieve the clamping function of the pliers 2, or they can be relatively far apart to achieve the opening function of the pliers 2.

[0039] As one optional implementation of this embodiment, the linkage mechanism 4 includes a linkage rod 41, a first connecting rod 42, and a second connecting rod 43. One end of the linkage rod 41 is connected to the operating handle 3, and the other end of the linkage rod 41 is rotatably connected to the first connecting rod 42 and the second connecting rod 43 respectively. The first connecting rod 42 is rotatably connected to the first clamping head 21, and the second connecting rod 43 is rotatably connected to the second clamping head 22. Since both the first clamping head 21 and the second clamping head 22 are rotatably connected to the housing 1 via a rotating shaft, when the linkage rod 41 moves, it can pull the first connecting rod 42 and the second connecting rod 43 to rotate. Since the first clamping head 21 and the second clamping head 22 are relatively fixed, the rotational motion can be converted into the opening and closing motion of the first clamping head 21 and the second clamping head 22, thereby realizing the clamping or releasing function of the clamping head 2.

[0040] In one optional embodiment of this invention, the first clamping head 21 has a first receiving groove 211 and a first through hole 212 communicating with the first receiving groove 211, and the second clamping head 22 has a second receiving groove 221 and a second through hole 222 communicating with the second receiving groove 221. The first receiving groove 211 and the second receiving groove 221 are used to facilitate the containment of foreign objects, thereby achieving the encapsulation and containment of foreign objects, while the first through hole 212 and the second through hole 222 allow blood to pass through.

[0041] In one optional embodiment of this invention, the housing 1 includes a first sleeve 11, a locking member 12, and a second sleeve 13. The first sleeve 11 is connected to the operating handle 3 and has a threaded section 111. The second sleeve 13 has a limiting portion 131. The locking member 12 has a receiving cavity 121, the inner wall of which abuts against the limiting portion 131, and the locking member 12 is threadedly connected to the threaded section 111. The locking member 12 can achieve a tight lock between the first sleeve 11 and the second sleeve 13. Specifically, the receiving cavity 121 cooperates with the limiting portion 131 to limit the second sleeve 13. The first sleeve 11 is equipped with a drive unit for moving the linkage rod 41. The first sleeve 11 is used to accommodate the linkage rod 41. The drive unit and the linkage rod 41 are detachably connected. When the pliers head 2 needs to be replaced, simply loosen the locking piece 12, remove the first sleeve 11 from the second sleeve 13, and then remove the linkage rod 41 from the drive unit. Then, a new pliers head 2 can be installed.

[0042] Please combine Figures 1 to 5 The specific operating principle of this utility model, as shown in the embodiment, is as follows: First, the doctor holds the grip ring 311 and pushes the second handle 32 to move. The end of the second handle 32 is engaged in the corresponding slot of the linkage rod 41. When the second handle 32 moves, it drives the linkage rod 41 to move along its length, thereby pulling the first connecting rod 42 and the second connecting rod 43 to rotate. Since the first clamping head 21 and the second clamping head 22 are relatively fixed, the rotational motion can be converted into the closing motion of the first clamping head 21 and the second clamping head 22, realizing the clamping function of the forceps head 2 on the foreign object. When the doctor releases the force, the second handle 32 can automatically reset under the action of the elastic force provided by the spring plate 33, thereby pulling the linkage rod 41 to reset. The first clamping head 21 and the second clamping head 22 move away from each other, thereby realizing the opening of the forceps head 2.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
